| Formula | Sets a question that expects
a formula to be typed in as an answer. The answer field
holds a formula for the correct answer, and the grading routine
checks that the given response evaluates to the same
formula. It accepts a formula (possibly a constant number, or simple
arithmetic expression). It does not accept equations (i.e.
``y=3x+2''). |
| Formula Mod C | This mode operates in the
same way as the Formula mode, except that it allows the
given answer to differ by a constant value from the answer in the
database. This mode is useful for questions on
integration. |
| Restricted Formula | This mode also
operates similarly to the Formula mode. However, only
arithmetic (+,-,*,/), exponentiation (^) and the
sqrt function may be used in formulas. This mode is
designed in order to ask questions like ``What is sin(Pi/4)?'' So
that the answer 1/sqrt(2) is acceptable, but ``sin(Pi/4)'' is
not. |
| Equation | Accepts an equation (e.g. y+3
= 4(x-1)). The answer provided in the test bank must be a ``simple
eqation'' (i.e. one side of the equation is a single variable with
nothing else [e.g. y=(4x-1)-3 and x=1+(y+3)/4 would both be
acceptable]). This restriction does not apply to the
equations the student gives as his/her response. |
| Multi Formula | Accepts a list of
formulas or numbers, separated by semicolons. The order of the
formulas does not matter. Thus, to give the solutions of x^2+x-1,
the student can write either
(-1 + sqrt(5))/2 ; (-1 - sqrt(5))/2
or
(-1 - sqrt(5))/2 ; (-1 + sqrt(5))/2 |
| Ntuple | Accepts an ordered list of
formulas or numbers within parentheses separated by commas. The
order of the formulas must be the same as in the correct
answer. This mode should be used for questions dealing with points
in space, etc. |
| Formula List | In a function, this is the
same as the Ntuple mode. The only difference is that
students get a slightly differently worded explanation of how they
should enter their answers, that emphasizes the terms as elements
of a list, not as coordinates of a point. |
| Plain Number | This mode accepts a number
(possibly in scientific notation). It does not allow arithmetic to
be used (except for scientific notation) e.g. 5*10^5 is acceptable,
3+4 is not. |
| Dimensioned Number | The
Dimensioned Number mode accepts numbers and formulas,
possibly including dimensions. It is able to recognize the
equivalence of many standard units (cm and meters, kg and g, etc.).
|
| Multiple Choice | Sets a multiple choice
question. Multiple choice questions must have an answer field and a
number of choice fields set. In this mode there can be
only one correct answer. |
| Non Permuting Multiple Choice | This is the
same as regular Multiple Choice mode , but the order of
the choices are not changed each time the question is set. |
| Multiple Selection | Similar to the
Multiple Choice mode, but the student must select all the true
responses from a list (which may be more than one, or none). |
| Non Permuting Multiple Selection | This is
the same as the regular Multiple Selection mode, but the order
of the choices is not changed each time the question is set. |
